GUIRegisterMsg ( msgID, "function" ) Parameters msgID A Windows Message ID (see Appendix: Windows Message Codes). function The name of the user function to call when the message appears or an empty string "" to unregister a message. Return Value Success: 1 Failure: 0 Remarks !!! To make the user function workable you have to define it with maximum 4 function parameters otherwise the function won't be called !!! i.e: Func MyUserFunction($hWndGUI, $MsgID, $WParam, $LParam) EndFunc Or Func MyUserFunction($hWndGUI, $MsgID) EndFunc When the user function is called then these 4 parameters have the following values: Position Parameter Meaning 1 hWnd The Window handle of the GUI in which the message appears. 2 Msg The Windows message ID. 3 wParam The first message parameter as hex value. 4 lParam The second message parameter as hex value. Up to 256 user functions can be registered for message ID's. By default after finishing the user function the AutoIt internal message handler will be proceed. That won't be if your Return a value (See WM_COMMAND in example) or if you use the keyword 'Return' without any value. By using 'Return' without any return value the AutoIt internal message handler (if there is one for this message) will NOT be proceed! !!! If you want AutoIt to run it's internal handler for a message, return the variable $GUI_RUNDEFMSG (in GUIConstantsEx.au3) from the function (see also examples) !!! I.e. if you want to return earlier than the user function ends and also proceed the AutoIt internal message handler. Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!! Some controls consume internally specific Windows Message ID, so registrating them will have no effect, e.g; WM_CHAR, WM_KEYDOWN, WM_KEYUP are consumed by an edit control.
